LUBRICATOR FOR LOCOMOTlVE-TRUCKS.

SPECIFICATION forming part of Letters Patent'N'o. 447,081, dated February 24, 1891.

Application filed August 22, 1890. Serial No. 362,709. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM MoINTosn, a citizen of the United States, residing at Vt nona, in the county of \Vinona and- State of Minnesota, have invented certain new and useful Improvements in Lubricators for L- comotive-Trucks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to lubricators for locomotive-trucks and similar bearings, and is directed to the oil-cellar and oil-supply pipes. In the engine-truck journal-box now in common use the oil-cellar is held in place by two cellar-bolts passing through flanges of the box and lugs on the cellar. lVhen the box and the cellar are new and the brass is of maximum thickness, the cellar fits closely to the journal, keeping the packing in contact therewith; but when the brass begins to wear by.

usage and the cellar-bolt holes become oblong by constant jarring the journal and the 25, cellar separate and keep going farther apart until the brass is worn out. Ofttimes there will be as much as an inch of space between the cellar and the journal. Hence at all times, except when the parts are new and closely fitted, there is a great waste of oil and the lubrication of the journal is very imperfeet.

The object of one feature of my invention is to overcome these defects by providing a .The journal-box is provided with four verticonstruction which will cause the oil-cellar to automatically adjust itself to the journal,

following up the wear of the brass and keepingthe packing at all times in contact with the journal. To this end I support the cellar from yokes spring-seated in the journal-box.

cal holes or recesses on its opposite corners, and U-shaped headed yokes provided with spiral springs encircling their stems are mounted in the'recesses. Forked pins entering transverse holes at the lower ends of the recesses serve as seats for the springs and to hold the yokes in position, the yokes fitting the forks or slotted opening in the heads of the pins. The forks also permit the yokes to pass upward beyond the pin-heads when the cellar is removed, which allows the pins to be withdrawn and the yokes taken from the recesses whenever so desired. The cellar is held bythumb-screws removably mounted in the cross-bars of the yokes, and to prevent the lateraldisplacement of the oil-cellarit is provided with mortise-shaped recesses on its under surface inline with the yokes, and the thumb-screws have chisel-shaped upper ends adapted to-fit in said recesses. This feature also prevents the thumb-screws from turning in the nuts. These thumb-screws both support the cellar and serve to adjust the tension of the yokes thereon as may be desired. They are preferably mounted in removable nuts which rest in corresponding seats on the upper surface of the yokes. These nut-seats on the yokes are perforated to a larger bore than the thnmb-screws,which permits the same to be easily removed. The outer ends of the thumb-screws are hookshaped or provided with eyelets'for co-operation with the cross-bar and hand-screw,working against the base-bar on the oil-box seat as a base of resistance to pull down the yokes against the upward pressure of the springs wheneverit is desired to remove the oil-cellar.

In order to supply the oil to the bearing without waste, I construct the supply-pipein three sections, two of which are rigid and a third flexible. The outer and larger of the rigid sections is fixed to the oil-box directly over the brass and is extended upward through an enlarged opening in the frame, so as to have sufficient clearance to, permit the frame to move without affecting the pipe. The other rigid section is smaller and telescopes within the outer section, having its open end terminating close to the lower end of the outer section. The flexible section is attached to the upper end of the smaller rigid section and extends to the oil-cup or other source of supply, which is preferably located on the front cross-bar of the engineframe or some other relatively-fixed part. The oil-cup is preferably of the force-feed variety. The advantage of this construction of the feed-pipes will be readily understood by all persons, familiar with the difficulties in theway of properly oiling enginetruck bearings. By this device the oil-cups may be Figure 1 is a sectional elevation of part of an engine-truck looking outward toward the rlght side. Fig. 2 is a frontviewof the same,

The lower :endof'the flexiblesection rests on the upper end of the outer'rigid section-R, thus suspendingthe inner rigid-section R'.

The operation is evidentfrom the descrip- 'tion already given. p

'In addition" to the advantages already nam'edit should'be noted that a" cellarof much less size and weight may be employed, much less packing is required, and there is practically no wearing out of any of the parts otherthan the brass,inasmuch as the springs compensate for all jarring. It should be further noted that the construction may be readily adapted-to the journal-box and cellars nowin common use.

Vhat I claim, and desire to secure by Letters Patentof the United States, is as follows:

1. The combination, with an oil-box provided with recesses, of yokes spring-seated in said recesses, and anoil-cellar supported by said yokes.

2. The combination, with the spring-seated yokes and the oil-cellar supported thereby, of a tension device for adjusting the "spring pressure.

3. The combination, witlr the spring-seated yokes and the oil-cellar supported thereby, of
